Abstract

An air temperature and humidity control device is provided including a heat pump and a humidity controller. The heat pump has a condenser, a first evaporator, a compressor, and a second evaporator. The humidity controller includes a first contactor fluidly coupled to the second evaporator. The first contactor includes at least one contact module having a porous sidewall that defines an internal space through which a liquid desiccant flows. A liquid source is coupled to the first contactor such that a second liquid provided by the liquid source flows through the first contactor adjacent an external side of the porous sidewall. Heat and/or water vapor transfers between the second liquid and the liquid desiccant.

First claim

The invention claimed is:

1. An air temperature and humidity control device comprising:
a heat pump including a condenser, an evaporator, and a compressor;
a humidity controller having a first contactor fluidly coupled to the evaporator, the first contactor including at least one contact module having a porous sidewall that defines an internal space through which a liquid desiccant flows; and
a vacuum pump coupled to the first contactor and configured to generate a pressure di…
